T. BAILEY, OF `BALLSTON SPA', NEW YORK.

KNITTING-MACHINE.

Specification `of Letters Patent No.

To @ZZ whom t may concern:

Be it known that I, TIMOTHY BAILEY, of Ballston Spa, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Machines Used in lthe Manufacture of Knit tion of the same, reference being had to the accompanying drawings, forming 4part of Figure l is an end elevation of the frame. Fig. 2 a front elevation of the same. Fig. 8 is a transverse vertical section, and Fig. 4,

lation to each other. e

Similar letters of reference indicate corresponding parts in each of the several iig- The form and arrangement of the `parts produce the fabric are for the most part which have always previous to my invention of the improvements herein specified been moved by the hands and feet` of an operative, my `said improvements consisting stantially such as herein described, for communicating motionto. the several parts from a revolving shaft driven by the constant application of any suitable power.

To enable others skilled in the art to make anduse my invention I will proceedto de- A, A, is the framingwhich carries allthe parts. z

B, is the main shaft, which is hung paral` lel to the front of the frame in bearings in the ends. It carries two cams O, O, one

formd grooves orchannels in each side viz: one D, on the inside for actuating the presser-bar, and another E, which assists in controlling the looks which willbe hereinthe outside for actuating the sinker-frame, the grooves on the outside and `those on the` inside of each cam being ofdifferent forms shaftI as ,the corresponding ones at the other 8,750, dated February 24, 1852.

one. D and E, are shown in Fig. 3, where theinside of the cam O,`is seen, and F, and G, are shown in Fig. l, where the outside of the cam O, is seen, the frame being broken `away to show them. The positions which D, and E, occupy in relation toF, and Gr, are shown in Fig. 4, where the black lines 1represent the form of the grooves D, and E, and the red lines of the grooves F, andG.

The cam O, is toothed on its periphery, which forms a toothed wheel gearing `with a pinion H, on an intermediate shaft I, on which there is a pulley J, intended to receive motion from the driving power shaft, the said pulley having a clutch attached to admit of the stopping and starting of the machine.

N,\N, are the hanging cheeks to which the sinker bar O, carrying the lead-sinkers .is attached. They are hung at their upper `ends on the ends of the top arms P, which are supported. upon standards Q. The back ends of the top arms have upright links R,

connected to them carrying studs and fric! tion rollers` b, which run in the grooves Gr, of thel cams O, and O. These links have slots in them which work on friction rollers a, see Fig. l, hung on stationary pivots secured in the frame, and serving as guides `to keep the friction rollers Z), in their` proper places in the grooves G; At their lower ends the hanging cheeksr are connected to horizontal rods S, .carrying studs at their `ends on which are friction rollers c, runningI in the grooves F,` ofthe cams.` lThe rods S, have slots in them which work on guidepins within the frame to keep them in proper` position.

CZ, are the leadesinkers whichfare sus-` pended from the sinker-bar O.`

nl. are` the jackesinkers, which are suspended on thejacks c. The jacks areall hung on acommon center rod or `pin j",

which together with the slur-bar g, the ackguides/L, and the jack-spring z', are all supported on a frame T, termed the camel, which has a cross end T2, fastened to it, shown bydotted lines, resting and traveling upon the top of two rollers T3 T3, which roll on the flange of the frame, and are held in their proper positions by 'two pins fastened in the plate t5, upon which they turn.

`The `plate t5 has two slots .in it which permit it to traverse upon the pins t4 t* secured into the cross end T2.` The sinker bar O, is

yconnected to the center rod or pin f, by linksA j, termed half-jacks, which causes all the sinkers and other moving parts connected with the camel constituting the sinker-frame to be drawn back and forth together by the movements of the hanging cheeks N, N, pro` duced by the grooves F in the cams C, and C. Another appendage to the frame of sinkers is the locker-bar P, which is for the purpose of raising the jack-sinkers at the proper moment, the only motion communr cated to them by their attachment to the sinker-bar O, being a movement back and forth. The locker bar P, is supported on the back ends of two levers Q, termed lockers, which are hung on the center rod The locker bar P is fastened to the lever Q by the screw Q2 and is adjusted to the desired height by the set screws p4 p". Attached to the front of the sinkerebar there are two hanging plates 7c, seen in Fig. 2, and in dotted lines in Fig. l, which perform the same office performed by the thumb plates used in the frame when operated by manual labor, and on the back of each of these there is a lip 4L which by the up and down movement of the sinker-bar O, is made to operate on the front ends of the lockers, being released from them when necessary by their lower ends coming in contact with 1nclined projections 5, in front of the frame. Below the sinker-frame there are two levers U, which hang on pins in standards Y, supported on the front part of the framing A, A. The ends of these levers carry studs and friction rollers Z, which run in the grooves E, of the cams C, and C. vUpright bars m,

are secured to the levers U, and to them arey secured catchesl n, (operated by the spring V2) which are intended to act on the back end of the lockers.

W, is the presser bar for closing the barbs of the needles at the time when it is reiquired to draw off the loops. The presserbackward forms levers, at the ends of which are suspended links Z, at the lower Vends of which are pins carrying friction rollers whichv run in the grooves D, the links being guided by slots in them, which work on friction rollers on pins o, secured in arms aty the back of the frame.

K, is the shaft hungin bearings in the ends of the frame, parallel with B', and receiving motion from it by means of a pinion L, on its aXis, gearing into a wheel M, on its own aXis. The pinion L, having only half the number of teeth of the wheel M, gives half a revolution to the shaft K, for every one of the shaft P. The object of the shaft K, is to transmit motion from the main shaft tothe slurs and thread leader.

y Therslurs p, for raising the tails ofy the jacks Vand depressing the jack-sinkers one after the other in succession to form the loops between the needle, slide on the slurbar g, in the usual manner and have a toothed rack bar g, attached below them which gears into the teeth of a toothed sector '11, which is secured upon a horizontal shaft s, placed at right angles to the shafts B, and K. This is best seen in Fig. 2, where the frame is broken away. On the same shaft s, there is a toothed pinion t, on each side of which there is an upright toothed rack. These toothed racks u and u slide in guides in a small stationary frame secured to the main stationary framing and lhave lugs v and e attached to them which are struck and forced down alternately by friction rollers on arms w; secured in positions diametrically opposite each other on the shaft K, one being opposite each lug. The racks being independent of each other,

when one is forced down it gives part of a v revolution to the pinion I?, raising the other rack ready to be operated upon at a suitable time by the other arm. the sector '11, receive motion with the pinion t, the sector giving motion in either direction to the rack bar Q, and theslurs. The rack bar near each end is widened for a short space, so that when the frame of sinkers ismoving back and forth it will not get out of gear with the sector.

ai, is the thread leader for laying the thread over'the needles preparatory to its having the loops formed in it. It consists of an arched piece perforated aty, y, to allow the thread to pass through, and is attached to a slide e, which travels along a bar 1,7eXtending all across the frame, above which it` is supported by standards 2, se` cured on the camel. The slide a, is attachedl to the rack bars g, by the crashed bows TT andis moved back and forth across the frame at the same time with it. slur carriage is connected to the rackl by vthe pieces b (projecting from the carriage) with pins passing through them and through the slots c c in the rack g. These slots allow the rack to move and carry the thread carrier -a proper distance in advance of the slur cock, `which elevates the back ends of the jacks and depresses the sinkers to form the loops between the needles. The operation of the parts which form the loops or stitches being precisely the same as in the hand frame, it will require no de.

scription here further than the manner in which the motions are communicated to them.v All the motions necessary to the leadsinkers are given by the grooves E, and Gr,v `tof the cams operating on the arms P, and S, the grooves G, being ofsuch form as to cause ,thetop armto give the necessary amount of. t1.

The shaft s, and

motion up and down to the hangingcheeksg.'

N and the grooves F, being ofsuch forni isoV `i'orth. The jack sinlers receive the requisite motion back and forth by the same means, being connected by the links or half jacks j tothe hanging cheeks N. These `motions are those usually given by the hand bar. The up and down motion of the jack-sinkers "is given by the united action of the locken bar and slurs, the lockers being operated by the lips 4, of the plates 7e, or by the catches n, attached to the uprights m, on the bars V, which are operated on by the grooves E, of the cams, and the slurs being moved once across by every revolution of the l5` cams in consequence of the movement communicated to them by the sector 1, and recelved by 1t through the pinion t, racks u,

i a', arms fw, fw, from the shaft K. The

presser-bar receives its only motion, viz: that `down upon the barbs of theneedles7 where it remains for a suitable time, being returned afterward ready for the next operation, through the grooves D, on the cams acting upon the lever ends of the bo-ws X. The thread guides receive the requisite motion for laying the thread for each row of loops or stitches through the same means as the slurs, being connected a's before described tothe rack bar operated.

The several devices and parts of the machine by which the motion of the `parts g, by which they are performing the work are produced being all properly arranged and adjusted in relation to each other, it is only necessary to supply the thread from a bobb-in in front of the frame and start the first row of stitches, when the work will be continued, and t-he machine will require no further attention than supplying with new threads or stopping in case of breakage of the thread or other derangement in the operation.

What I claim as my invention and desire to secure by Letters Patent is l. Releasing the hanging plates 7c from the lever Q by the inclined projections 5 as they are drawn up, so asV to let the uprights m and lever U raise the locking bar.

2. The combination `of the catch n (fas-Y tenedto the upright m) spring V2, lever U operated by the groove E in the cam to raise the` locking bar so as to allow' the slur to operate and depress the sinkers to divide the loops and form the stitches, and to raise the lever Q so as to be caught by the lip 4`upon the plate k to lock down the locking bar.

In testimony whereof I have hereunto signed myname before two subscribing witnesses. y
